So I discovered why my recently manual swapped 300D's clutch was not disengaging. .

I opened the access cover and felt bits of metal and plastic. This led me to believe it was the throw out bearing. I proceeded to drop the trans, and upon removal, the bearing was ok. However the pilot bearing exploded. The outer race was still in the crank, and the inner race was non existant. The bearing holder was still intact but only found 1 ball bearing. So I removed the pressure plate, and clutch disc to discover that the clutch disc was also destroyed. The contact surface was ok, but the center was cracked and a spring also came out.

My question is, How this could have happened?

Ill upload a few pictures later

My guess is that one of the clutch springs failed first. I had one let-go not too long ago. .02

Yes, I've seen clutch diaphragm fingers break off and jam up the works.

What stumped me is that all the fingers were ok. No marks or any signs of damage. As soon as I find my camera Ill take a few pictures
